Such problems are difficult to diagnose and the few things that you need to pay attention to are :
1. Alternator. Get the charging tested. Since you had to replace the battery, it could be a charging fault and when battery gets drained, it would fail. With a new battery, if the charging rate is no good, it would fail soon.
2. Fuel system. It could be a failing fuelp pump, relay or its wiring circuit.
3. Ignition switch. A failing ignition swich can cause intermittent stalling and non starting.
